Application filed April 22, 1925. Serial No. 24,994.

My invention relates to lasts and in particular to snap back lasts.

It is the object of my invention to provide a snap back last which will have its last parts positively and firmly maintained in predetermined relationship to one another and its parts positively moved into expanded positions. By positively I mean that the parts are movable under tension of a very strong spring which under ordinary circumstances is quite similar to a positive actuating means.

It is a further object of my invention to provide a snap back last in wiich the connecting parts and spring will occupy the minimum of space which becomes a matter of advantage in lasts of certain types and design.

Referring to the drawings:

Figure l is a side elevation of the last partially in section to show the arrangoment of the spring and links; and

Figure 2 is a plan view of the spring and link construction.

Referring to the drawings in detail, 1 is a toe part and 2 is a heel part of the last. These last parts are limited in their expanded position by the shoulders 3 and a.

Above these shoulders on the toe part is a semi-circular transverse groove 5 adapted to receive a projecting circular shoulder 6 above which are the spaced faces 7 and 8 of the last halves which are so spaced to permit of the collapsing of the last halves.

The center of this shoulder is provided with a hinge pin 9 while the last half is provided with anchor pins 10 and 11 located below the hinge pin and so arranged that the line drawn between the centers of the anchor pins will always be below the center of the pin 9. Mounted on these anchor pins is a spring which has an arched center 12 and a forwardly and downwardly descending portion 12 which terminates in it The spring then proceeds upwardly as at 14 to the rear of the anchor .pin 11 and over the anchor pin to form a hook 15. Returning to the arch 11 of the spring it will be noted that it descends as at 16 beneath the anchor pin 10 and over the anchor pin 10 to form a hook 17.

Embracing the spring on its rear end are the spaced links 18 having their rear ends mounted on the anchor pin 10 and their for ward ends to the hinge pin 9. Similar links 19 embrace the sides of the spring at the forward end, the forward ends of said links being mounted on the anchor pin 11 and the rear ends on the hinge pin 9.

It will be understood that I desire to coinprehend within my invention such modifications as may be 1 necessary to adapt it to varying conditions of use.

Having thus f" lly described my invention, what I claim as new and desire to secure by Letters Patent, is

l, in a last, a toe part, a heel part, said parts beii r arranged to rock on one another, yiek means adapted to tend to maintain. said parts in expanded position and to hold them together, anchor pins in the respective parts of the last over which the ends of said spring are hook-ed, said spring consisting of an inverted U-shaped centra portion, the forward arm of which descends to a point below the forward an. chor pin to form a tip and then forwardly over the anchor pin to form a hook, and the rear arm of which descends downwardly below the rear anchor pin and thence upwardly to form a hook.

2. In a last, a toe part, a heel part, said parts being arranged to rock on'one an-' other, yielding means adapted to tend to maintain said parts in expanded position and to hold them together, anchor pins in the respective parts of the last over which the ends of said spring are hooked, said spring consisting of an inverted U-shaped central. portion, the forward. arm of which descends to a point below the forward anchor pin to form a tip and then forwardly over the anchor pin toform a hook, and the rear arm of which descends downwardly below the rear anchor pin and thence upwardly to form a hook, a hinge pin located in one of said parts within the U-shaped central portion of the spring, links mounted thereon, anchor pins carried in the respective last parts for supporting said links, said anchor pins being so arranged that a line drawn between the centers thereof will never pass over the center of the hinge pin.

In testimony whereof I afiix my signa- GEORG'E GLAUSING. -v
